“…There are existing studies on different postharvest treatments, but in this study, the effect of combination treatment using cold temperature, a physical control method, was tested to increase the efficiency of D. suzukii control using EF [ 2 ]. The effects of EF differ according to the developmental stage of many insects [ 32 , 37 , 38 , 39 ].…”

“…Spotted-wing drosophila ( Drosophila suzukii ) originated in East Asia but is currently found on all continents [ 1 ]. However, postharvest treatments can help reduce the spread of the pest within continents and in countries where it does not yet occur [ 2 , 3 ]. D. suzukii lay eggs on fruits, and the hatching larvae burrow into the fruit, making the detection of infection difficult at the early stage.…”

“…In general, quarantine disinfection to control D. suzukii is performed chemically by using fumigants such as methyl bromide (MB), phosphine (PH 3 ), and ethyl formate (EF) or by various physical controls such as heat treatment, low-temperature treatment, and irradiation treatment [ 2 , 8 , 9 , 10 ].…”

Drosophila suzukii is a quarantine pest that is rapidly spreading in berries. This study evaluated the synergistic effect of combination treatment with ethyl formate (EF) and cold temperature for D. suzukii control on imported grapes. A higher insecticidal effect was observed at 1 °C than at 5 °C at all developmental stages, and the pupal stage showed the strongest tolerance to cold temperature. After EF fumigation alone, eggs showed the highest tolerance at 216.67 mg·h/L (LCT99 value), and adults showed the highest susceptibility at <27.24 mg·h/L. Among the combination treatment methods, cold temperature after fumigation resulted in the best synergistic effect. The effect of this combination was significant, with 23.3% higher mortality for eggs, 22.4% for larvae, and 23.4% for pupae than observed with EF fumigation alone. Furthermore, the period of complete D. suzukii control in the 12 L desiccator was shorter in the combination treatment group at the LCT80 value than at the LCT50 value of the egg stage. EF showed a very high sorption rate (24%) after 4 h of exposure at a grape loading ratio of 15% in a 0.65 m3 fumigation chamber. As the grape loading ratio for combination treatment decreased, D. suzukii mortality increased, but when EF was administered at the LCT80 value, there was little difference in the mortalities of the eggs and larvae but not the pupae. All D. suzukii developmental stages were completely controlled within 7 days after combination treatment, and phytotoxicity was not observed in grapes. These results suggest that the combination of cold-temperature treatment and EF fumigation could be used for D. suzukii control.

Combined Effects of Cold Treatment and Phosphine in Drosophila suzukii (Diptera: Drosophilidae)

This study analyzed the effect of combined phosphine (PH3) fumigation and low-temperature treatment on the control of Drosophila suzukii. In the low-temperature, single-treatment experiment, there was no significant difference in insecticidal activity between 1 °C and 5 °C except in D. suzukii adults. Adults showed 98.0% mortality after exposure to 1 °C for 7 d. Regarding fumigation treatment with PH3 alone, adults were the most susceptible, and pupae had the highest tolerance. Combined low-temperature treatment and fumigation showed a synergistic effect, except in the egg stage, and showed slight synergistic effects in larvae and pupae regardless of the combined treatment order. In pupae, the combination group exposed to 1 °C for 24 h after exposure to PH3 for 4 h had the lowest LCT99 value, at 10.49 mg·h/L. The sorption rate of PH3 on grapes decreased to 85.49% after 4 h of exposure, with a 15% loading ratio (w/v), and there was no significant difference in various criteria of phytotoxicity in exposed grapes compared to control, even after 14 d of combined treatment. Therefore, this study indicates that combined PH3 fumigation and low-temperature treatment could be useful in D. suzukii control.

“…Therefore, in addition to post-harvest methods for organic farmers and producers, some field-level tactics, such as using cultural and IPM methods and introducing biological control agents (i.e., parasitoids, predators, and pathogens), have been adopted. Some post-harvest methods and strategies against SWD have been proposed [14]. However, they are not efficient in preventing the post-harvest losses of sweet cherry due to this pest.…”

Efficient strategies are required in sweet cherry fruits to control the spotted wing drosophila (SWD), Drosophila suzukii, due to its adverse economic effect on farmers. Cold storage (CS) and storage with elevated carbon dioxide (CO2) are environmentally safe approaches for the pest control of stored fresh fruit. These strategies are effective in controlling a wide variety of insect species, without allowing toxic compounds to accumulate. The purpose of this study was to assess the effectiveness of a post-harvest application of CO2 treatment at 50%, cold treatment at 4 °C (CT), and a combination of both (CO2-CT) in controlling the early stages of SWD within four cultivars of freshly harvested cherry fruit, namely “Burlat-Bigarreau”, “Giorgia”, “Ferrovia”, and “Lapins”. In addition, an evaluation of the quality attributes of the cherries (skin firmness, berry firmness, strong soluble material, and titratable acidity) was carried out at harvest and after 10 and 20 days of storage. All treatments significantly reduced the rate of emergence of SWD when compared to the control (untreated cherry at 24 °C), and 100% SWD mortality was obtained in Burlat-Bigarreau (CO2-CT). In addition, over the entire storage time, the quality parameters were preserved in the samples stored at 4 °C and in the samples with combined treatments in comparison with the control.
